4 Claims.

This invention relates to window constructions, particularly forvehicles, as the cars of stream line trains, and has for its object aweather tight mounting for the sash in the frame, and more particularlya weather tight mounting for the rounding corners of the sash in therounding corners of the window frame.

It further has for its object a weather tight mounting for a sash in awindow frame with rounding corners, which weather strip is composed offlexible resilient material, as rubber, and is in the form of a channelfitting in the channel of the window frame and receiving within it thesash,'the weather strip having beads or heads at the margin of its sidewalls, which beads are pressed tightly against the sash or the glassthereof forming a weather tight glazing strip, with the mounting beingso constructed that when the strip is bent around the corners of thesash Figure 2 is an enlarged fragmentary isometric ed in the windowopenings of the car body in any suitable manner, this frame beingusually formed of metal to provide a channel 2 for receiving the sash,one wall 3 of the channel being demount- 5 able for the purpose ofreplacing the sash in the window or removing it therefrom.

By sash is meant a glass pane, single or double,

with or without a marginal frame.

As here illustrated, the demountable side 3 fits in a groove 4 in thewindow frame beyond the bottom of the channel 2 and is held in thegroove by a screw 6.

8 designates the sash frame, this being usually I formed of metal andbeing formed with a channel 1 9 for receiving the margin of the glassI0. As

here shown, the sash is formed with a double glass pane with a spacer llbetween them.

The construction of the sash frame per se formsno part of thisinvention.

The margins of the glass pane may fit in an inner weather or glazingstrip l! in the channel of the sash frame, as shown in the applicationofRoy T. Axe, Serial No.- 103,560, filed October 1, 1936.

13 designates the flexible and resilient weather tight mounting stripfor the sash in the window frame.

The window. frame and the sash are formed with rounding corners, andthis invention relates to the construction .of the weather strip, where-15 by the weather strip, when bent, around the rounding corners, fits,without distortion, against the sash or the glass thereof. The strip I3is U-shaped in cross section and fits into the channel 2, and the sashframe 8, when in position, I snugly fits the weather strip and pressesit against the sides and the bottom of the channel 2. The sides of theU-formation of the strip I: are provided'with headed or beaded portionsll located beyond the inner edges l5 of the sidewalls of the channel 2of the window frame, these beaded portions l4 pressing against the sashframe or the glass thereof. The beaded portions coact with the edges" ofthe side walls of the channel 2 of the window frame, so that the beadedportions are pressed against the sash or the glass thereof,

The mounting strip I3 is made upin straight strips U-shaped in crosssection, and when applied to the window and sash frame is bent aroundthe rounding, corners of the channel 2 of the window frame. and therounding corners of the sash frame. Ordinarily, this would causedistortion and buckling of the strip at the corhers, and particularlydistortion of the beaded portions at the corners, so that the beaded 0portions would not lie snugly against the sash or the glass thereof, andthe margins of the side walls of the channel 2- of the window frame. Inorder to cause these beaded portions ll to snugly, without distortion,lie against the sash or the glass thereof and against the margins of theside walls of the channel 2 around the corner portions thereof, thestrip l3 at the corner portions thereof is formed with transverse slitsl6 through the bottom portion of the channel formation 50 thereof, theslits extending partly into the side walls of the U-formation of thestrip, so that when the strip .is bent around the corners of the sashand the frame, these slits open and permit the U-shaped strip I! tobend, without dis- 55 torting the beaded portions l4. Hence, when theinstallation is complete, the beaded portions, 0

with a window frame in the form of a channel, Y

the frame having rounding corners, and a sash mounted in the channel andhaving rounding corners; of a mounting and weather strip in the channelin which the sash is mounted, said strip being in the form of a channelfitting the chan- -nel in the frame and having the edges of its sidewalls in the form of beads pressing against the sash and the'outer edgesof the side walls of the channel of the frame and forming glazingstrips, the channel-shaped strips being formed with transverse slits inthe bottom portion thereof at the corners of the window frame and thesash.

2. In a window construction, the combination with a window frame in theform of a channel,

the frame having rounding corners, and a sash mounted in, the channeland having rounding corners; of a mounting and weather strip in thechannel in which the sash is mounted, said strip being in the form of achannel around the periphery of the sash and embracing the sash,thestrip fitting the channel in the frame and hav-' ing the edges of itsside walls. in the form of beads pressing against the sash, said stripbeing formed with transverse slits in the bottom portion thereof at thecorners of the window frame and the sash for causing the beads'to followthe rounding corner portion of the sash, without distortion, and topress against the sash.

3. In a window construction, the combination with a window frame in theform of a channel,

the frame having rounding corners, and a sash- -mounted in the channeland having rounding corners; of a flexible cushion mounting andresilient weather strip in the channel in which the sash is mounted,said strip being in the form of a channel and fitting the channel in theframe and having the edges of its side walls in the -form of beadscoacting with the walls of the channel of the frame to press the beadsagainst the sash, said strip being formed with transverse slits in thebottom portion thereof. at the corners of the window frame to cause thebeaded portions to press evenly against the sash and the window frame atthe corners, without distortion.

4. In a window construction, the combination with a window frame-in theform of a channel,

the frame having rounding corners, and a sash mounted in the channel andhaving rounding corners; of a flexible cushion mounting and resilientweather strip in the-channel in which the sash is mounted, said stripbeing initially straight in the form of a channel in cross section andbeing fitted in the channel of the frame and around the corners thereofand embracing the margin of the sash, the strip having beads at.

the edges of its side walls pressing against .the

sash, the strip being constructed to cause the beads to be continuous atthe corners of the sash and the frame, without buckling or distortion.
